I occasionally browse the “Discover” tab, but now I notice that there is no Bulgarian language in the drop-down menu:
And I want to add my Discourse forum there, but my forum is in Bulgarian… and somehow it’s not good to add it under another language. If anyone can share whether the option for forums in Bulgarian will be added, and whether there are any requirements. If not, then someone should share why this option is not there. 
Edit:
I found what the requirements are, and yes, I have turned the option on. Apparently it takes longer and will require patience.
Thank you for your time.
